Horses seem to know this; for if you should by chance catch one asleep he seems very indignant either with you or himself.
It was absolutely necessary to give our horses a day's rest, as they looked so much out of sorts this morning.

A quarter of the day was spent in watering them, and by that time it was quite hot, and we had to erect an awning for shade.

We were overrun by ants, and pestered by flies, so in self-defence we took another walk into the gullies, revisited the aboriginal National Gallery of paintings and hieroglyphics, and then returned to our shade and our ants.

Again we pored over the little German map, and again envied more prosperous explorers.

The thermometer had stood at 101 degrees in the shade, and the greatest pleasure we experienced that day was to see the orb of day descend.
